Flexible display panel and method of manufacturing the same

Abstract

A flexible display panel and a method of manufacturing the same are disclosed. In one aspect, the flexible display panel includes a flexible substrate configured to display an image. The display also includes a first layer formed over a first surface of the flexible substrate and configured to compress horizontally with a compressive strain force. The display further includes an adhesive interposed between the flexible substrate and the first layer.

         1 . A flexible display panel, comprising:
 a flexible substrate configured to display an image;   a first layer formed over a first surface of the flexible substrate and configured to compress horizontally with a compressive strain force; and   an adhesive interposed between the flexible substrate and the first layer.   
     
     
         2 . The flexible display panel as claimed in  claim 1 , wherein the adhesive is configured to attach the first layer to the first surface of the flexible substrate. 
     
     
         3 . The flexible display panel as claimed in  claim 1 , further comprising a polarizing film formed over a second surface of the flexible substrate. 
     
     
         4 . The flexible display as claimed in  claim 3 , wherein the flexible substrate and first layer are bendable towards the polarizing film. 
     
     
         5 . The flexible display panel as claimed in  claim 1 , further comprising a protective film formed over the first surface of the flexible substrate and configured to block moisture transmission,
 wherein the first layer is disposed between the flexible substrate and the protective film.   
     
     
         6 . The flexible display panel as claimed in  claim 1 , wherein the flexible substrate has a portion of the first surface folded or bent in a direction facing the remaining portion of the first surface. 
     
     
         7 . A method for manufacturing a flexible display panel comprising:
 forming a first layer;   coating an adhesive on a first surface of the first layer; and   providing a flexible substrate having first and second surfaces on the adhesive, wherein the first surface and the second surface face each other,   wherein the first layer is configured to compress horizontally with a compressive strain force.   
     
     
         8 . The method as claimed in  claim 7 , further comprising providing a polarizing film on the second surface of the flexible substrate. 
     
     
         9 . The method as claimed in  claim 7 , wherein the first layer is attached to the first surface of the flexible substrate by the adhesive in a tensioned state by a tensile force. 
     
     
         10 . The method as claimed in  claim 7 , wherein the first layer is attached to the first surface of the flexible substrate by the adhesive in a heated and expanded state. 
     
     
         11 . The method as claimed in  claim 7 , wherein the flexible substrate is configured to display an image through the first surface of the flexible substrate. 
     
     
         12 . The method as claimed in  claim 7 , wherein the flexible substrate has a portion of the first surface that is folded or bends in a direction facing a remaining portion of the first surface. 
     
     
         13 . The method as claimed in  claim 7 , further comprising stretching the first layer such that the stretched first layer has a predetermined tensile force. 
     
     
         14 . The method as claimed in  claim 13 , wherein the tensile force and the compressive strain force apply in opposite directions. 
     
     
         15 . The method as claimed in  claim 7 , further comprising heating the first layer such that the first layer expands, before coating the adhesive on the first surface of the first layer. 
     
     
         16 . A flexible display panel, comprising:
 a flexible substrate configured to display an image;   a first layer formed over a first surface of the flexible substrate and configured to compress horizontally;   a protective film formed over the first surface of the flexible substrate and configured to block moisture transmission;   a first adhesive layer interposed between the protective film and the first layer; and   a second adhesive layer interposed between the first layer and the flexible substrate.   
     
     
         17 . The flexible display panel as claimed in  claim 16 , wherein the flexible substrate has a substantially uniform thickness throughout the flexible display panel, and wherein the first layer has a substantially uniform thickness throughout the flexible display panel. 
     
     
         18 . The flexible display panel as claimed in  claim 17 , wherein the flexible substrate and the first layer are bendable towards the polarizing film. 
     
     
         19 . The flexible display panel as claimed in  claim 18 , further comprising a polarizing film formed over a second surface of the flexible substrate, wherein the first and second surfaces of the flexible substrate oppose to each other.
